server.js — Express API

const express = require('express')

const app = express()

// Middleware pipeline

app.use(authMiddleware)

app.use(rateLimiter)

app.use(validateRequest)

// Routes

app.get('/api/users', async (req, res) => {

const users = await db.find()

res.json({ success: true, users })

})

app.listen(3000, () => {

console.log('🚀 Server ready')

})

How Express Works

The Middleware Pipeline.

Every request flows through a chain of middleware — auth, validation, logging, and more — before reaching your route handler. We design these pipelines to be airtight.

Common Questions.

What is Express.js best for?

Express is the go-to framework for building REST APIs, GraphQL servers, and microservices in Node.js — minimal, fast, and highly flexible.

Express vs NestJS or Fastify?

Express gives maximum control with minimal overhead. We choose the right tool per project — Express for flexibility, Fastify for raw throughput, NestJS for opinionated enterprise structure.

How do you handle API security?

Every API we ship includes JWT auth, rate limiting, input validation, Helmet.js headers, CORS policies, and dependency audits as standard.

Do you provide API documentation?

Yes — we generate Swagger/OpenAPI docs automatically and maintain them alongside the code, so your documentation never falls out of sync.
